"You'll be scrapped in the morning, you silly engine!"
-Mr. Railway Man
Mr. Railway Man was a corrupt railway controller and the leader of the Diesel Army.
At some point, Mr. Railway Man (his real name is unknown) befriended Mr. Green, and the two made The Diesel Army together. Mr. Railway Man was controlling the British Railways by day, and making the Diesel Army by night. He apparently robbed ships as well, and he and Green became known as the LNER Pirates by Crabbestal.
Mr. Railway Man claimes he will scrap Connor after his accident occured, as he was too expensive to maintain. The next day when Connor ran away, Railway Man was very frustrated. He eventually confronted Connor and tried to destroy him with help of Diesel and some fuel tankers, and ultimately failed, and was chased away by the authorities.
Mr. Railway Man continued his conquest to eradicate steam with assistance of his army, mainly stationed on Tankopia. He managed to track down and capture Connor, Ivo Hugh, 089 and Lady. They all escaped and Railway Man was nearly killed during the destruction of the building, Diesel Headquarters II. Eventually Railway Man was pushed to the side of the army by the popularity of D199 amongst the ranks. After seeing what his creation had become, Railway Man eventually gave in and helped destroy it. He was to help destroy the engines of Sodor with a tank, but ended up using it to destroy Spencer and a bridge, perishing in the process.
